How do you change colors for multiple layers at one time?

There are two options to do so..


      Set_Layers_Outline_Color\n
      6-2,9-3,10-4\n

That will set layer 6 to color 2, layer 9 to color 3, layer 10 to color 4.

 
      Set_Layers_Outline_Color\n
      6-1234 5678 9012,9-9876 5432 123,10-4567 321 89\n

That will set layer 6 to RGB color (1234,5678,9012), Layer 9 to RGB color (9876,5432,123), 
and Layer 10 to RGB color (4567,321,89).
